Integrated passive seismic acquisition and methodology. Case Studies

Passive seismic uses natural microseismicity as seismic sources and stand-alone receivers (seismographs), which are laid out on the surface of the target area in such a way that they can produce results with maximum achievable resolution. Consequently, the passive seismic methodology is characterized by three main advantages over conventional seismic methodologies: it is cost effective, it is environmentally friendly and it is easily applicable, even in areas with the most difficult terrain. The procedure of a passive seismic project can be divided into four basic steps: (a) a preacquisition (feasibility) study (b) acquisition and data analysis (assuming the presence of suitable natural seismicity) (c) an inversion process and (d) quality control (QC) of the results. A detailed description of these steps is presented here.
